What are the advantages of pneumatic gate valves?

The flexible and reliable pneumatic manual switching mechanism is equipped with the pneumatic manual switching mechanism on the upper part of the cylinder head, so that at any position during the opening and closing process of the gate valve, the operating handle can be easily rotated to directly perform the operation from pneumatic to manual or from manual to pneumatic. conversion of the operation mode. The conversion operating handle adopts a positioning pin type self-locking design, which is reliable and stable after the handle is positioned. If the solenoid valve and its control circuit or the air supply system fails, it can be quickly converted into a manual operation state without other auxiliary tools, so as to ensure the normal operation of the circuit and avoid accidents. Before the self-control system of the new construction is completed, the pneumatic gate valve can be used as a manual gate valve reliably, and the action is flexible and brisk.
